Review on Gallon Aquarium Divider Suction Cups by Amy Moore

Had to buy a 10 gallon bulkhead for a 5 gallon tank for 2 men. I used rubber cutting scissors to cut it to size. I had to use a handsaw to cut the plastic support to size. It would be 5 stars if inserting the pins was a little easier. I used a drill to widen the hole a bit and it worked great. The suction power is excellent. He moves! That's what makes him on the spot in the first place. I installed in an empty tank. I would recommend even if you need to trim it. Other dividers on the market are just terrible.
